Definitions
- the present invention relates to the field of heat shrinkable tubular articles such as sleeves and the use thereof. More specifically, the invention provides an improved lubricant and method of using the lubricant, especially in conjunction with the application of heat shrinkable sleeves to electrical wires and cables.
- Heat shrinkable sleeves and their use are well known.
- heat shrinkable sleeves and associated devices are disclosed in the U.S. Pat. Nos. 3,894,731, 4,868,023, 4,712,721, 4,478,252, 4,349,404, 3,894,731, 2,027,962, 4,969,402, and 4,514,031, all incorporated herein by reference for all purposes.
- Such sleeves are used, for example, to protect cable splices from environmental attack, and to provide visual markings for identification of a particular wire or group of wires.
- Commercially, such sleeves are represented by the Thermofit® marker system manufactured by the assignee of the present invention.
- One method of applying heat shrinkable sleeves involves the use of a carrier of the sleeves such as a bandolier.
- Heat shrinkable sleeves are affixed to the bandolier for ease of handling.
- the bandolier enables markkng of the heat shrinkable sleeves for later installation on and identification of a particular cable or wire.
- a technician can easily slide the sleeve off of the bandolier, and apply the marked sleeve to a cable or wire.
- the sleeve may then be heated or otherwise treated at a later convenient time so as to firmly attach it to the wire or cable and/or to permatize the indicia marked on it.
- the sleeve is preferably sized such that it fits snugly on the bandolier to prevent sliding off of the sleeve before it is marked. However, if the sleeve fits too snugly on the bandolier, removal of the sleeve from the bandolier is sometimes difficult. Accordingly, various lubricants have been applied to the sleeve and/or the bandolier to facilitate removal of the sleeve.
- lubricants have been applied by dispersing the lubricant in a suitable organic carrier and applying the dispersed lubricant to the inner surface of the sleeve and/or to the outer surface of the bandolier.
- a suitable organic carrier Normally such lubricants are dispersed in a low boiling point chlorofluorocarbon such as material marketed under the name Freon*.
- chlorofluorocarbons present an environmental threat, primarily resulting from ozone depletion. Accordingly, many industries are attempting to reduce or eliminate the use of chlorofluorocarbons to abate global warming and ozone depletion. Efforts to replace chlorofluorocarbons have, however, been directed primarily at the largest volume users of such materials. For example, replacements for Freon as a refrigerant, and replacements for the various chlorofluorocarbons used in the electronic industry as cleaning solvents have been proposed. These efforts have not addressed in a substantial way the needs of industries which use chlorofluorocarbons as a lubricant carrier, however.
- An improved lubricating composition and an improved method of lubricating heat shrinkable sleeves on a bandolier and other surfaces is provided by virtue of the present invention.
- the invention provides an environmentally safe replacement for chlorofluorocarbon based dispersants for lubricants.
- the lubricant is easily used and provides for a low frictional force between two lubricated surfaces.
- the lubricant is an aqueous dispersion.
- the dispersion includes an appropriate lubricant, which in a preferred embodiment is calcium stearate and a surfactant that provides appropriate surface tension characteristics.
- the surfactant reduces the surface tension of the dispersion to less than about 75 dynes/cm. preferably less than about 50 dynes/cm, and more preferably less than about 30 dynes/cm.
- the surfactant is sodium dioctyl sulfosuccinate or a fluorinated alkyl polyoxethylene ethanol.
- Heat shrinkable sleeves and a method of applying heat shrinkable sleeves to a substrate are also provided by virtue of the present invention.
- a heat shrinkable sleeve is applied to an application substrate.
- the sleeve is marked, and then slid off of the application substrate for placement on a wire, cable, or similar electrical or optical conductor.
- the application substrate and/or the sleeve is lubricated with an aqueous dispersion of a metal stearate and a surfactant.
- FIG. 1 is a drawing illustrating use of the invention with a bandolier/heat shrinkable sleeve

- the lubricating dispersion is preferably prepared by mixing the water, lubricant, and surfactant at ambient temperature, followed by vigorous agitation.
- the lubricant is preferably applied to the inner surface of the tube by circulating the lubricant dispersion through an uncut roll of tubing, followed by circulation of air through the uncut tubing to blow out and evaporate the aqueous component of the dispersion (e.g., for 10 minutes).
- the lubricant is applied to the application substrate by spraying, followed by drying of the application substrate. A combination of the above methods may be used in some embodiments.
- the tubing is cut in appropriate lengths for application to the substrate.
- Each length of tubing (sleeve) is then slid on to a finger of the substrate, and if necessary the tubing is partially shrunk by appropriate application of heat.
- the tubing is shrunk at least enough so that when the fingers are placed in a downward facing position the sleeve will not fall off of the fingers.
- the tubing is shrunk to the point where the sleeve substantially matches the abutting contours of the fingers. The finger prevents the sleeve from recovering completely. This process is referred to as "restricted" recovery.
- the substrate is fed into a typewriter, computer printer, or other suitable printing means for application of appropriate labeling on each sleeve.
- the sleeve is subsequently removed from the substrate.
- the user may simply grasp the tubing and pull the tubing off of the substrate.
- the tubing is grasped with a suitable tool such as shown in FIG. 1.
- the tubing is then applied to the cable, and is shrunk further by application of additional heat, radiation, or the like using means known to those of skill in the art.
- the objective of this experiment was to determine the pull out force (in lbs) of tubing on a nylon bandolier after partial recovery using H 2 O+5% calcium stearate and 0.2% aerosol ot.
- Tubing sizes of 3/32", 1/4", 3/8", and 1/2" were utilized made from two types of compounds (polyolefin and fluoropolymer) to give a general understanding of lubricity as a function of surface area and types of compounds utilized. Parameters of the various experiments are listed in Table 1.
- aqueous dispersion comprised of H 2 O+5% by weight calcium stearate and 0.2% by weight aqueous solution of 10% sodium dioctyl sulfosuccinate was mixed vigorously in a plastic container for 5 minutes and then poured inside the sample tubing. The tubing sample was clamped at both ends and shaken for 10 seconds. After 10 seconds, the dispersion was poured back into the container and the tubing was left to dry for 30 minutes at 23° C. The tubing was then cut to length, placed on the bandolier, recovered, and pulled off of the bandolier. The force required to pull the tubing off of the bandolier was measured by the force gauge shown in FIG. 3.
- the force for removal of the tubing from the substrate is measured by removing the tubing from the substrate with a removal bracket that is similar to the tool shown in FIG. 1 and used with the TMS® system.
- the bracket is attached to a conventional force measurement gauge 22, which indicates the force (in pounds according to the experiments herein) that is being applied to the tubing as it is pulled off of the substrate.
- the aqueous dispersion proved to be a satisfactory replacement for CFC TF 113 type Freon from Dupont as shown in Table 3. Accordingly, not only will the aqueous lubricant dispersions described herein be environmentally acceptable, but they will often provide superior performance.
- a water process which varied from the one described above was utilized. The process differed in that the lubricant was placed on the bandolier. Laboratory experimentation indicated that a pre-punched nylon carrier immersed for 10 seconds in a water dispersion of calcium stearate (5% calcium stearate w/w and 0.2% w/w of 10% aqueous sodium dioctyl sulfosuccinate), resulted in acceptable pull out forces.
- Table 4 summarizes the results. The results show higher, but acceptable, pull out forces when the lubricant is applied to the bandolier fingers directly.
